Saffer Solutions is run by Ethan Saffer, a licensed Professional Engineer working in power utility substation design. Everything sold here comes out of real project work — practical tools built to catch the mistakes that slip through design reviews, not theory.

The General Engineering Design Review Checklist is distilled from years of running design reviews, and it isn't tied to one discipline — it works across engineering design: 56 items across 8 sections, from kickoff through design development to closeout, in a clean printable PDF you can run on every job.
